Description

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with NHEJ1-related conditions. This variant is present in population databases (rs372722590, gnomAD 0.007%). This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 183 of the NHEJ1 protein (p.Pro183Ser).
